# Scan numbers for raw data of Figure 3

Figure 3a/b (Birefringence):

Files: Data/Birefringence_Data/FeSe_Warmup3_20211014_20x/FeSe_20211014_50K_StrainLoop1/Images/Image_Data/FeSe_20211014_50K_StrainLoop2_BirefRes_i.txt for i = 0 to 100.

Corresponding simultaneous resistivity data/piezo voltages/capacitance are in file:
Data/Birefringence_Data/FeSe_20211014_50K_StrainLoop1/FeSe_20211014_50K_StrainLoop1_BirefRes.txt
Each row of data maps sequentially to the corresponding image number.

Images for all strains are autocorrelated for spatial overlap and images are normalized by the fully detwinned reference image ('0') as a background. Plotted images are on '50' (0.00%) and '100' (0.22%) after background normalization.
